Obverse Dies: 6 Known
A better date in the Seated Dime series and challenging to locate in grades of EF or higher. The Large O has historically been more available than the Medium O, which is rare in EF or better. However a significant number of Medium O dimes have surfaced recently.
Six different obverse and reverse dies have been identified for 1856 New Orleans coinage.
Plate Coin: Fortin 101, Large O, Difficult Variety in Mint State, Incredible Original Toning, Satiny Luster, Predominantly Blue, Green Obverse Tone, Reddish Orange on the Reverse
The 1856-O Dime has a large mintage of over a million pieces but, like many of the New Orleans mint issues of this period, it is hard to find in high grade. PCGS has certified fewer than two dozen Mint State examples of this date, most of which are MS64. The typical 1856-O Dime is well-struck, though the occasional example may show weakness on some of the denticles. The finest known 1856-O Dime is a single PCGS MS-66.
The mintmarks on this date appear in two different sizes: Medium O and Large O. Of the nine die varieties described by Jerry Fortin, three have repunched dates.
